With a decisive victory in Illinois, Mitt Romney is firmly in the driver's seat of the Republican presidential nomination contest.

In a victory speech in Schaumburg, Ill., the former Massachusetts governor thanked his Republican opponents, but very quickly pivoted to the general election against President Obama.

"It's time to say this word," said Romney. "Enough. We've had enough... We need a president who believes in us."

This Romney speech even sounded different. With Romney restating the big ideals of his campaign, it sounded like an acceptance speech.

Romney painted Obama as a law professor with no business experience and he offered himself as a "real choice and a new beginning." He said he had the "experience and the vision to get us out of this mess."

He called on Americans to join him and he presented a grand platform with his vision for America.

"I see an America," he said, "that is humble but never humbled."

This was a sweeping victory for Romney, too.

"Mr. Romney bested his chief rival among many types of voters, winning among men, women, and voters of all ages, the exit polls show," The New York Times reported. "Mr. Romney drew the support of more moderate voters — as he has in the past — but also won among voters who said they were supportive of the Tea Party movement."

His main rival, however, dug in. Former Pennsylvania Sen. Rick Santorum delivered a defiant and cutting speech, despite the fact that Romney also solidified a great lead in delegates.

"We don't need a manager," said Santorum in his Gettysburg, Pa., speech. "We need someone who's going to pull out government by the roots and throw it out."

On more than one occasion, Santorum compared Romney to Obama. He took shots at Romney, saying his health care program is interchangeable with Obama's health care program. He said Americans don't need a politician who says what "pollsters tell them to say or what's on their teleprompter."

We live blogged Tuesday night. If you want a blow-by-blow account of how it went down, keep reading.

Update at 9:55 p.m. ET. Digging In:

In the end, Santorum's speech just meant that he was digging in, despite a race that is increasingly likely to go Romney's way.

Santorum closed his speech tonight, by outlining just why he's running for the nomination. He said it's because this election is the most important since the election of 1860, which saw Abraham Lincoln take office and was held just before the Civil War broke out.

Santorum said he ran for office because "we don't want to be the generation that lost the torch of freedom."

Update at 9:45 p.m. ET. 'We Don't Need A Manager':

Santorum very quickly moves on to attack Romney.

"We don't need a manager," said Santorum. "We need someone who's going to pull out government by the roots and throw it out."

On more than one occasion, Santorum compared Romney to Obama. He took shots at Romney, saying his health care program is interchangeable with Obama's health care program. He said Americans don't need a politician who says what "pollsters tell them to say or what's on their teleprompter."

Update at 9:41 p.m. ET. We Won Conservative Areas:

Rick Santorum, taking the stage in Gettysburg, Pa., says he's proud of his performance in Illinois.

"We won the areas that conservative Republicans populate. We're very happy about that" he said.

Update at 9:36 p.m. ET. Romney Maintains A Huge Lead:

With 48 percent of precincts counted, Romney still has a huge 17-point lead. Romney has 49.9 percent of the vote, while Santorum follows with 32.6 percent.

Update at 9:26 p.m. ET. Replacing A Law Professor:

Romney now makes the case that he his the man to make the American government leaner and less intrusive.

"I'm going to change that," he said. "We're going to get government out of the way."

Romney painted Obama as a law professor with no business experience and he offered himself as a "real choice and a new beginning." He said he had the "experience and the vision to get us out of this mess."

The former governor's speech sounded very different tonight. It sounded like a relaunching of a campaign, or, in other words, an acceptance speech. He called on Americans to join him and he presented a grand platform with his vision for America.

"I see an America," he said, "that is humble but never humbled."

Update at 9:18 p.m. ET. 'What A Night':

"What a night," Romney says in his victory speech. "Thank you Illinois."

Romney congratulated his Republican opponents. But Romney very quickly pivoted to attack President Obama.

"It's time to say this word," said Romney. "Enough. We've had enough... We need a president who believes in us."

Update at 9:14 p.m. ET. 'Happy Anniversary':

Ann Romney takes the stage and gives her thanks to Romney. She says tomorrow is the couple's 43 wedding anniversary.

"Happy anniversary, sweetheart," she says.

Romney and his wife took the stage in Schaumburg, Ill., to raucous applause.

Update at 9:03 p.m. ET. The Delegate Count:

Illinois voters will actually vote on both the candidate and then select delegates who will represent them at the convention. Those delegates are labeled with the candidate they are supporting.

So, explains The New York Times' Nate Silver, the presidential preference ballot is technically a beauty contest. Silver reports on some of the delegate results:

"So far, 10 Congressional districts have reported a material amount of results in Illinois, all of them in the Chicago area. Mr. Romney's delegates lead the race in each one of these districts, which would account for 28 delegates total."

"The campaign moves to Louisiana, which holds its primary on Saturday. Romney has struggled in the Deep South, and a poll released by the Republican Magellan Strategies on Monday had Santorum leading Romney by 13 points in the state."

We're also waiting on speeches from the candidates. Santorum is in his home state of Pennsylvania and Romney is in Illinois.

"Mr. Romney bested his chief rival among many types of voters, winning among men, women, and voters of all ages, the exit polls show. Mr. Romney drew the support of more moderate voters - as he has in the past - but also won among voters who said they were supportive of the Tea Party movement."

This win, the Times says, will give Romney some pretty solid ammunition to say that this primary contest must end in order to focus on the general election fight with President Obama.

Update at 8:43 p.m. ET. AP Projects Romney Wins:

The AP has now joined Fox and CNN projecting Romney will win Illinois. The wire service adds:

"Exit poll results show Romney was preferred by Illinois primary-goers who said the economy was the top issue in the campaign. The former Massachusetts governor also was overwhelmingly favored by those who said an ability to defeat President Barack Obama was the quality they most wanted in a GOP nominee."

Update at 8:41 p.m. ET. Fox News, CNN Project Romney Wins:

Based on exit polls and very early returns, CNN and Fox News are projecting that Mitt Romney will win Illinois.

Update at 8:25 p.m. ET. First Results Are In:

Results have started trickling in. With 0.6 percent of the precincts reporting, Romney has 54 percent of the vote and Santorum has 26.8 percent. Paul is in third place with 10.2 percent of the vote.

Update at 8:21 p.m. ET. The Experience Candidate:

The Washington Post's Chris Cillizza picks up on a shift in the race. He says Romney's "experience" argument — that he is the man with experience to turn this economy around — is working. Cillizza reports:

"Roughly one in five Illinois Republican voters said that a candidate having the right experience was the most important trait for them in deciding who to vote for. Of that group, Romney won 62 percent of the vote as compared to 19 percent for former House Speaker Newt Gingrich and just 8 percent for Santorum."

Previously, Gingrich had won that vote. Now that he's fading as a candidate, Romney, not Santorum, has picked up those voters.

Update at 8:11 p.m. ET. Romney's Campaign Spending:

The AP notes that as has been the case throughout this campaign, Romney has severely outspent Santorum:

"His campaign and Restore Our Future, a super political action committee that supports him, outspent Santorum and his super PAC by $3.5 million to $500,000, an advantage of 7-1."

"According to the exit poll, 32 percent of Illinois votes decided whom to vote for either just today or in the last few days. While that is not a spectacularly high figure, it is larger than in most other recent states."

CNN also couched its exit poll numbers saying the later waves of voters polled have tended to vote for Santorum.

"The turnout was heavier in Republican strongholds, where voters went to the polls knowing they would play an important role in the battle between Mitt Romney and Rick Santorum for the GOP presidential nomination," the paper reports.

Update at 7:43 p.m. ET. NPR's Delegate Count:

We've seen some questions on Twitter about NPR's delegate count. Indeed, it differs from other news organizations. Here's the why for that difference:

"NPR's delegate tracker awards only those delegates who are committed to voting for a candidate at the Republican National Convention through at least the first ballot. It does not estimate delegate allocation based on straw polls that frequently accompany early rounds of caucus events. Nor does it attempt to track preferences of 'unpledged' RNC members that by definition cannot be bound to a candidate. These guidelines distinguish it from delegate counts in other media."

"Exit polls showed more than 70% of the state's voters were from suburban areas, where Romney has done well in previous GOP contests. They also indicated Romney leading among more affluent and more educated voters, while Santorum led among rural voters and those who considered themselves 'very conservative.'"

Update at 7:19 p.m. ET. What's At Stake Tonight?

Our congressional editor S.V. Date tells us that 54 delegates are at stake tonight. "The state has 69 total," he says. "But 15 cannot be bound."

And, where do we stand so far? 771 delegates have been awarded and here's how that breaks down:

-- Romney has 416.

-- Santorum has 183.

-- Newt Gingrich has 136.

-- Ron Paul has 34.

The two that complete the math were awarded to Jon Huntsman before he exited the race.

Update at 7:02 p.m. ET. Ballot Problems:

Results may be slow to come tonight. The Washington Post reports that 25 of the state's 110 voting juridictions have ballots that are too wide to be fed through optical scanning machines.

"After the polls close this evening, workers will probably have to hand-trim the ballots — or hand count them," reports the Post.
